VenTech’s, Carbon Charcoal
Growing cannabis indoors has plenty of advantages., IE. Can grow weed 365 days out of a year, complete control over the growing area and environment. (Temperature, lighting, water, etc.)
Still, growing weed indoors does have a major problem-Smell!
Indoor growing may smell up your house and also attract unwanted and potentially dangerous attention from your neighbors. So, odor control is essential. That’s why a quality carbon filter and a working inline duct fan is a must.
Why Are CO2 Filters Necessary?
A working CO2 filter rids the grow area of smells and contaminants, like pollen, dust, and spores. It does this via charcoal that acts as a sponge that traps the obnoxious smells and other pollutants.
Ventech Company Background
It is among the cheapest on Amazon.
Is this CO2 filter, which comes in 4″ and 6″ models, something you should consider buying? Or, should you stay with a more well-known carbon filter? I will answer this and more in my review.

Pros and Cons
- Overall, very high ratings
- All reviews that specifically mentioned that it was being used for a grow room gave the Ventech a top rating for grow area smell control.
- Reasonable price
- Solid construction, and overall mad well
- Eco-Friendly- It is reusable and is stated to last up to 18 months of use.
- Not For Indoors? VenTech on their listing has a disclaimer stating that this should NOT be used in enclosed areas. I’m pretty confident that this is just CYA, lawyer, crap. But, it still makes me a bit wary.
- Filter Design-Multiple reviewers stated that the Ventech, which uses virgin charcoal, was packed too loosely, which resulted in it spilling out and making a big mess when it was taken out of the box. A reviewer even said that the leak even contaminated his grow room’s inline duct fan.
- Lasting- A few low reviews stated that it only worked for around a month to six months when it says it is supposed to work for 1 and 1/2 years.
- Not-Activated- It uses virgin charcoal, which is another word for non-treated non-activated charcoal. Active is considered to work better than its non-activated counterpart. Look at the appendix for more info.
- Warranty- They only have a 90 day, money-back guarantee. VenTech does not mention what happens after the 90 days. (Many companies would give you a replacement and not a refund after the warranty has expired) However, this product is stated to last for 18 months. So, I don’t know what would happen if it stops working on the 91st day?
I would recommend this reviewed the Ventech for the following reasons:
- High Amazon rating
- Top-20 Amazon bestseller rating
- Excellent rating for the user’s mentioning that it was being used for a grow room.
- Very Reasonable price
Overall, Ventech makes an excellent, low-priced, carbon filter, and I would recommend it for any home grower.

Ventech Inline Fan
If you decide to purchase this model you may want to consider also purchasing Ventech’s inline duct fan. Their inline duct fan is reasonably priced and has an air flow rating of 420 CFM and is designed to work with Ventech’s Carbon Filter. For more information, check out my review.
Activate vs. Non-Activated Charcoal
The two most common types of charcoal are activated and non-activated. (AKA Virgin Charcoal-Ventech’s Co2 filter uses virgin charcoal.) I will briefly go over the differences between the two charcoal types.
Non-activated or virgin charcoal is not prepared or treated before it is sold. On the other hand, charcoal is considered activated when chemically treated by gas. This chemical treatment results in enlarging the charcoal’s surface. Between the two, activated charcoal, as it is more porous, will work better in controlling odor and otherwise help in improving the overall airflow.
